Techstream ECU Flash Reprogramming Procedure
Int roduction
Flash reprogramming allows the ECU software to be updated without replacing the ECU. Flash
cali bration updates for specific vehicle models/ECUs are released as field-fix procedures described
in individual Service Bu lletins. This bulletin details the Techstream ECU flash reprogramming
process and outlines use of the Technical Information System (TIS) and the Calibratio n Update
Wizard (C UW) . Flash calibration updates can only be applied to the vehicle/ECU combination for
which they are intended . ECUs have internal security that will not allow them to be programmed with
another ECU's information.
ECU
Electro nic Control Unit (ECU ) is a Lexus term used to describe integrated computerized devices
responsible for managing th e operation of a system or subsystem . For th e purposes of this
bulletin , the term " ECU" is us ed as a generic label for the following SAE J1930 standard references :
• Powe rtrain Control Mod u le (PCM)
• Engine Control Module (ECM)
• Transmission Control Modul e (TCM)
• Or any other Lexus spec ific control unit

3. Select the correct Interfa ce Setup from the drop down list.
• If using Techstream 2.0, select MongoosePro MFC.
• If using Techstream Lite, select Mongoose MFC or MongoosePro MFC (depending on the
cable being used).
NOTE
Mo ngoose Driver MUST be installed before Mongoose select ions will be available.
See TIS - Diagnostics - Scantoo/ page for addit ional informat ion .
• If using TIS Techstream, select TIS Techstream VIM.
4. Click OK.
Process Overvi ew
Techstream ECU flash reprogramming is a 4-step process:
1. Verify the vehicle's applica bility for recalibration and locate desired calibration file by performing
the Techstream Health Check function.
NOTE
Techstream will automatically search TIS for the appropriate Serv ice Bullet in usi ng the
current Calibratio n ID from the vehicle. Calibratio n fi le lin ks ca n be fo und em bedded in th e
corresponding Service Bulletin.
2. Connect the GR8 Battery Diagnostic Station using "Power Supply Mode" only.
The GR8 Battery Diagnostic Station includes a Power Supply Mode to help maintain battery
voltage at 13.5 volts during ECU reprogramming.
NOTICE
ECU damage may occur if th e correct battery charger m ode setting i s NOT used .
3. Locate appropriate calibration ID and reprogram the vehicle ECU with Techstream.
Techstream uses the Calibration Update Wizard (CUW) application to open calibration fi les and
fa cilitate the ECU flash reprogramming process.
4. Attach the Authorized Vehicle Modification Label.
Modifications to ECU calibrations MUST be recorded and properly displayed on the vehicle using
the Authorized Modification Label.
